-.-To all whom it may concern:

. citizen of the United States, residing at- Philadelphia, int-he county of Philadelphialan'd state' of Pennsylvania, have invented a certain new and useful System of Develop:

f inglNaturallower for Industrial Purposes,

(if-which the-following is a specification.

- 1 .I-Ieretofore and before my invention it f-swells, and wave eti'ects' for obtaining use-- gful encrgy,but-sogfar as 1* am aware none has been pifoposed to utilize tidal changes,

ofjtlie devices-s01iroposed has been comnierciullyqfsuc ess ful owing to their ex- "treuiely low lli'ciencyli This is due principullyl'to "the factith at mechanical movements aweref einp'loyed avhichat times operated at high speed, a d at other times were -idle. Otherwise stated theo'pcration was irregular owing to 'the changing conditions of=the water -power.'-; The. dcsideratnm, therefore,

is a plantof the character referred to, the

, opcriition'of-whicli will be constant and hence high-in eilici"ncy.' L

My, ivention contemplates this among other things, and mor e specifically stated Qit .comprellemls an air compressor system whereof the compression cylinders are curricd by a that and cooperate with water columns 'whichi act as pistons or plungers to compress, the air. Other objects, as well as the nature, characteristic features, and scope of the invention will more readily be understood from .the following description taken in connee-' t-ion; with the accompanying drawings,

wherein:

Figure 1, is a sectional elcvational view showing the general arrangement of the apparatus. Rig. 2,-is a vertical sectional view of one of the air-compression cylinders; and Fig. 3, is a view on the line 3-3 of Fig. 2, more particularly showing the adjusting screws for varying the .area of compression.

I erect at some suitable point along the coast, a concrete or other solid and stable founclation 5, which supports a suitable sea \all or break-water (5, within which the machinery is-mounted and properly housed and otherwise protected against the action'of the elements. There are openings or passages I, in the wall (3,-for the ingress and egress of water, and said openings are equippednvith gates 8, which, may be opers ecmean n r Letters r te'iti fatcnted 29, 1912.

'Theiflotit is composed of a decktl2, and hull,o;- b dy 13, therefor, eonstitutedpr'eferably of.-water,-' 55 tight compartments which mayibefilletlhor' emptiedof water in the well knewnz ia iue to properly ballastthe fio V The latter is equipped with arms or slides 1 t;- 7 'th rollers 15, and it will be observedguponirefe ence to Fig. 1, that the posts r =guidesf ,1 constitute tracks for s aidslidesiihdifol so that the float, is free to grespondj to, the rise and fall, of ,the,water. gSuitable, t. or lulmpers 16, ,inaybe ,providedftin path of the slides-14, andwhenpresent serve to limit ,the downwardm' n1 t f .the floats if p 'Below'the float and rigidly-54m the concrete foundation 5,.areuprightlcylindrical tanks, shells, or casing s;l 7, ;wherpof the number may vary according tofltlicsize and capacity of the. plant to be They are provided with water intakes 18;, and with stuffing-boxes 19.. -'lhe'waterfca sj- 86 ings 17, constitute one principal'factor or element of an air compressor, another prins cipal element being the air compression .cylf inders 20-, which are rigidly secured tothe -flo ut and telescopc'the water cylinders 17.

(aps 21, are provided for the cylindersjQO 1 and they have air-inlet nozzles 22, equip e j with snitablycheck provisions. QManifes ly,1 as the float rises in response to arising;

i n'iovement ofits fluid supporuair will be'fifi drawn into the compression cylinder, and will lie-compressed by the column of water in the cylinder 17 when the float descends.

I propose to provide for regulating-the i I area of compression. This may be accomplished in variousways, but for the sake of illustration, I have shown the caps 21, as telescoping the compression' cylinders 20, and equipped with a pacltingming 23, and with regulating screws 24 ,nnd hand wheels 105 25, by means of which'the capsmay be advnnccd or retracted.

26, to a high pressure receiver or reservoir 11 .units 29, 30, etc.

, anchored below the float and having water 7 equipped ivith a pressure indicator '28;

and with other necessary adjuncts, and from whence it is supplied to converters or power It will be obvious to those-skilled in the art to which the invention relates. that various changes and" modifications may be made Without departing from the spirit and scope otth'e inventifo'n. Hence the same is not. limited'other than required by the state of the prior art. 7

Having described the nature and objects of the invention, I claim,

1. Means for compressingair, comprising a float responsive to waive m'oti0n, cylinder s intakes and means to prevent-the outflow of water, and compression cylinders-secured to the float and telescopingEsaid first mentioned cylinders and equippedf with suitable check 7 provisions.

2. Means for compressing air, comprising a floatj'responsive-to wave motion, cylinders anchored belowthe float and havingwater intakes and ineansto prevent the outflow of water, compression cylinders secured to the float and telescoping said first mentloned cylinders and equipped :with suitablecheck provisions and means for regulating the area of com i'ession. f i 3. Means or compressing air,.comprising a suitable inclosure 'oi" breakwater with means for the ingress and e ress of Water, a float adapted and arrange to reciprocate therein in response :to the rise and fall of water, compression cylinders secured to the 1g r r 1,036,502-
